liquid solution: soda

solid solution: stell.

compound: salt.

coloid: milk.

element: aluminum foil.

Explanation:

Solutions are homogeneous combination of two components, a solute (the one in lower proportion) and a solvent (the one in bigger proportion). Soda is solution composed by water (solvent) and carbonic acid (solute). Steel is a solid combination of Iron (solvent) and Carbon (solute).

A compound is a molecule composed by 2 or more different elements. Here, salt (NaCl) is composed by Sodium (Na) and Chlorine (Cl).

Coloids are systems, apparently homogeneous, but when you look deeper you can detect different phases. This is the case of milk which is a fluid with proteins and differents components constituting different phases.

Finally an element is a form of materia in which there is only one atom. Aluminum foil is an example of this.
